Please read each manual relevant to your purpose. Safety Precautions This instruction manual describes the operation and function of the KV Series PLC. Read this manual carefully to ensure safe use and maximum performance from your KV Series PLC. Symbols The following symbols alert you to important messages. Be sure to read these messages carefully. Failure to follow instructions may lead to injury. (electric WARNING shock, burn, etc.) CAUTION Note: Failure to follow instructions may lead to product damage. Provides additional information on proper operation. Conventions This manual describes the operation/function of all Keyence KV Series PLC. Note following conventions when you use. Visual KV (Series) KV-10xx, 16xx, 24xx, 40xx KV-10AR/AT/DR/DT KV-24AR/AT/DR/DT KV-16AR/AT/DR/DT KV-40AR/AT/DR/DT Conventional KV (Series) KV-300 (Series) KV-10/80 (Series) KV-10R(W)/T(W) KV-24R(W)/T(W) KV-80R(W)/T(W) KV-300 KV-16R(W)/T(W) KV-40R(W)/T(W) General Precautions • At startup and during operation, be sure to monitor the functions and performance of the KV Sereis PLC. • We recommend that you take substantial safety measures to avoid any damage in the event a problem occurs. • Do not open or modify the KV Series PLC or use it in any way other than described in the specifications. • When the KV Series PLC is used in combination with other instruments, functions and performance may be degraded, depending on operating conditions and the surrounding environment. • Do not use the KV Series PLC for the purpose of protecting the human body. Note: The built-in display may show the error message "Error 40" blinking the very first time you turn on the power supply to the Visual KV Series. Press any key around the display to cancel this message. The Visual KV Series shows this message when no program is loaded. (1) Note to User When using the Visual KV Series in the following conditions or environments, be sure to use the Visual KV Series with sufficient margin regarding the rating and functions, take appropriate safety precautions such as fail-safe, and contact our sales personnel if any questions arise. • Use in conditions or environments not described in this manual • Use for nuclear power control, railway facilities, air service facilities, vehicles, combustion devices, medical equipment, amusement machines, safety equipment, etc. • Use for applications where large effects are predicted to be given on human lives and properties and safety is especially requested. Restriction on Acquiring the CE Marking ■ Restriction to be compatible with EMC directives • When using a relay output type unit (whose model name ends with "R"), connect spark killers having the appropriate withstand voltage against the load to the output terminals in parallel to contacts (because the unit discharges when a relay contact becomes open and noise is generated). In our experiments, we use the following models of spark killers. XEB0101 0.1 µF-10 Ω manufactured by OKAYA DENKI SANGYO The following 1-turn ferrite core is added to the AC power input circuit of the KV40AR/T, the KV-24AR/T and to the DC power input circuit of the KV-40DR/T. ZCAT3035-1330 manufactured by TDK Note: The contents above do not by themselves ensure that the entire machine manufactured in accordance with the above contents is compatible with EMC directives. You must judge by yourself whether or not the entire machine is compatible with EMC directives because compatibility may change depending on the component configuration, wiring and location inside of the machine. ■ Restriction on compatibility with low-voltage directives (IEC-1010-1) • Use insulated type crimp-style terminals. • For wiring materials, use lead wires whose sheath is 0.4 mm or more. • The Visual KV Series is allowed to be installed in a vertical position only. (Spacers for expansion units are not available.) • Be sure to use the Visual KV Series inside the control panel. (2) Features of the Visual KV Series ● Extremely small The Visual KV Series is the smallest in the world among AC type PLCs equipped with screw terminal blocks, and saves installation space. ● Extremely fast The minimum scan time is 140 µs and minimum instruction execution time is 0.7 µs, which is the fastest control in its class. ● AC power built-in type newly added AC power built-in type units are newly added. This type can be used in small spaces where a switching power supply unit cannot be installed. ● Excellent Access Window An Access Window with two-color backlight is adopted in all models to facilitate changing and monitoring of device data. Changing between RUN mode and PROGRAM mode, checking the error code when an error has occurred, etc. can be performed in a Visual KV Series unit without the need for any handheld programmer. The analog trimmer, which has been popular in the conventional KV Series, is digitized to enable more detail settings. [Digital trimmers] ● User message setting function In the Access Window, 256 different user messages can be displayed. This function can be used to give instructions on works on the production line, indicate abnormalities in the units, etc. ● Program write in RUN mode Ladder programs can be changed even while the system is running. ● Equipped with two serial ports Visual KV Series basic units are equipped with two serial ports to connect peripheral units, improving the debug environment. (The KV-10xx is equipped with only one serial port.) ● Easy Ramp-up/down control function The one-axis motor control function is offered separately from high-speed counters so that feedback control is enabled. ● Equipped with two 24-bit high-speed 30 kHz, two-phase counters The Visual KV Series is equipped with two high-speed counters each with a twopoint comparator output function that enables high-speed encoder input. ● Specified frequency pulse output function High-speed counters can function as pulse oscillators of 50 kHz maximum with easy setting, without creating a complicated ladder program. ● Frequency counter function High-speed counters can function as frequency counters with easy setting, without creating complicated ladder programs. ● Cam switch function High-speed counters can function as cam switches with easy setting, without creating complicated ladder programs. (3) ● Interrupt function The Visual KV Series is equipped with four high-speed interrupt inputs of 10 µs maximum. ● Input time constant change function The time constant can be set in 7 steps from 10 µs to 10 ms. ● Double memory backup functions In addition to a conventional SRAM battery backup function, the Visual KV Series is also equipped with an EEPROM backup function. Compatibility with Conventional KV Series Peripheral Units The Visual KV Series functions as a high-end compatible model of the conventional KV Series. Peripheral units of the conventional KV Series such as the ladder support software "KV IncrediWare (DOS)" and "LADDER BUILDER for KV" and the handheld programmer KV-P3E(01) can be used since they are part of the Visual KV Series. However, it should be noted that the contents have changed as follows. • The internal clock cycle of high-speed counters consists of three types: 1 µs, 10 µs, and 100 µs. • The time constant for an input relay specified by the HSP instruction is 10 µs. • The analog trimmer function is set with the Access Window built into the basic unit. • The available device setting range of the TMIN instruction is from 0 to 65535. [Handheld programmer KV-P3E(01) can display 0 to 9999 .] • The RUN/PROGRAM LED is displayed in the Access Window provided on the front face of the basic unit. • Transistor output is not independent, but is common. • With the transistor type, the output terminal layout is different. • The specifications for output current of transistor outputs Nos. 500 to 502 is 100 mA. • Conventional KV Series expansion units are not available as expansion units for the Visual KV Series. • The channel setting switch is not provided for expansion units. Channels are determined in connection order. • Scans in expansion I/O units are not synchronous with the scan time in Visual KV Series basic units. • Assignment of special utility relays has partially changed. • Data memory device Nos. DM1000 to DM1999 are assigned as special data memories. (4) Cautions when using the previous version of ladder support software Pay strict attention to the following items when using the ladder support software. • • CAUTION When using the ladder support software "KV IncrediWare (DOS)" or "LADDER BUILDER for KV Ver. 1.0x", set the model to "KV-300". DM0 to DM1999 are only available. When the ladder support software "LADDER BUILDER for KV Ver. 1.0x" is used, do not use the monitor’s Change All function. If the Change All function is used, the basic unit may be damaged. Never use the Change All function. Peripheral units and other units incompatible with the Visual KV Series Peripheral units in the conventional KV Series and other units shown below are not compatible with the Visual KV Series. • • Expansion I/O units for the conventional KV Series: KV-8ER/8ET/8EX/16EX/ 8EYR/8EYT/16EYR/16EYT Analog I/O units for the conventional KV Series: KV-AD4/DA4 Cautions when Using the Serial Port The KV-16xx/24xx/40xx units are equipped with two RJ-11 modular connectors for serial communication. When using them, pay strict attention to the following contents: (5) • Programs can be transferred and monitored using either communication port A or B. However, never connect the ladder software and a handheld programmer to the two ports at the same time. • The KV-D20 operator interface panel can be connected to either communication port A or B. However, only one KV-D20 unit can be connected to a single basic unit. • Never leave both the KV-D20 operator interface panel and KV-P3E(01) handheld programmer on simultaneously for a long period of time.

Includes the internal current consumption and current consumption of expansion units. Note: The maximum output capacity available with the AC type service power output is the output capacity of each basic unit subtracted by the internal current consumption of the basic unit, connected expansion units, and connected peripheral units. Visual KV Series operation at power interruption ■ Drop in supply voltage When the supply voltage drops, the Visual KV Series stops operating and the output turns off. ■ Detection of instantaneous power interruption • An AC type basic unit continues operating against instantaneous power interruption of less than 40 ms. A DC type basic unit continues operating against instantaneous power interruption of less than 2 ms. • An AC type basic unit may or may not accept instantaneous power interruption of 40 ms or more. A DC type basic unit may or may not accept instantaneous power interruption of 2 ms or more. • When accepting instantaneous power interruption, a basic unit stops operating and the output turns off. ■ Automatic recovery • Once the supply voltage recovers, the Visual KV Series restarts operation automatically. ▲ Rated voltage ▲ Instantaneous power interruption: Less than 40 ms Rated voltage ▲ Rated voltage ▲ Instantaneous power interruption: 40 ms or more Rated voltage Note: If the supply voltage increases gradually or drops, the Visual KV Series may repeat operation and then stop. If problems continue to occur with equipment and other operations from repetitive starts and stops, provide a protection circuit so that the output shuts down until the voltage reaches the rated value. ■ Time until start of operation • The time period from when the power is turned on until operation starts varies depending on the conditions, including the supply voltage, system configuration, and operating environment. The minimum time is approximately 1.2 ms. • When a user program is changed, it will be saved in the EEPROM when the power is next turned on. Therefore, in such a case, the time period from when the power is turned on until operation starts is longer than usual.

Never use the Change All function. 1-6 Chapter 1 Configuration and Specifications 1.2 Specifications ■ Electrical double-layer capacitor built into the basic unit Contents of data memories, current values of counters, and the contents of internal utility relays in a Visual KV Series basic unit are saved in RAM backed up with an electrical double-layer capacitor built into the Visual KV Series basic unit by the Data backup function against instantaneous power interruption. The backup time varies depending on the ambient temperature. Visual KV Series Data backup function against instantaneous power interruption If power to the Visual KV Series basic unit remains OFF for more than the holding time by the RAM, the data may be cleared or become corrupted. To avoid the data being cleared, save the data in the EEPROM using the backup function to the EEPROM. ➮ For writing to and reading from the EEPROM, refer to "LOAD mode and SAVE mode" (p.1-96). When a user program is written, it is saved in RAM. The next time the power is turned on, the user program is automatically transferred from RAM to the EEPROM and is also saved in the EEPROM. If power to the Visual KV Series basic unit will remain OFF for more than the backup time by the RAM, turn the power off immediately after writing a user program, and then turn the power on again so that the user program is transferred to the EEPROM. • Data backup function by electrical double-layer capacitor built into the basic unit Visual KV Series: 2 months or more at 25°C (77°F) (20 days or more at 25°C (77°F) in KV-10xx) ■ EEPROM The Visual KV Series basic unit is equipped with a backup function to save programs, contents of data memories, current values of counters, etc. in the EEPROM. Even if the power is interrupted or power to the Visual KV Series basic unit remains OFF, the data is still saved. When the power turns ON again, the contents of the EEPROM is automatically read. (The contents of data memories and current values of counters should be read by manipulating the Access Window.) When data is changed and the power is turned off without saving the changed data, the changes are saved only in the built-in electrical double-layer capacitor and are not saved in the EEPROM. If the Visual KV Series basic unit remains OFF for 2 months or more at 25°C (77°F) (20 days or more at 25°C (77°F) in KV-10xx) while the data is backed up only with the built-in electrical double-layer capacitor, the saved contents may be cleared or become corrupted. If the Visual KV Series basic unit will remain OFF for a long period of time, save the data in the EEPROM. ➮ Refer to "LOAD mode and SAVE mode" (p.1-96). • Data backup function with the EEPROM Visual KV Series: 10 years or more at 25°C (77°F) (available number of overwrites: 100,000 times or more) Chapter 1 Configuration and Specifications 1-7 11 1.3 Common I/O Specifications of Basic Units Visual KV Series 1.3 Common I/O Specifications of Basic Units This section describes the common I/O specifications of Visual KV Series basic units.

Note 2: Ensure sufficient ventilation space so that the power supply can release heat. Note 3: Never install a unit just above any equipment which generates a lot of heat. Chapter 2 System Installation 1-65 2.1 Installation Environment 2.1.3 Installation Procedure This section describes how to attach a connected unit directly to a panel, to a DIN rail, or to a DIN rail with an expansion unit spacer. Visual KV Series ■ Attaching a unit directly to a panel Attach the metal fixture for screw tightening to each KV Series unit using the countersunk-head screws through the countersunk holes. Mount the fixture directly to the panel. ■ Attaching a unit to a DIN rail Hang an upper claw of a Visual KV Series basic unit to the upper side of the DIN rail, and press the basic unit onto the DIN rain until a click sound is heard. 2 ■ Removing a unit from a DIN rail Pull a lower claw of a Visual KV Series basic unit downward from the front direction using a screwdriver, and then remove the basic unit from the DIN rail. Expansion unit spacer When an expansion unit spacer is attached to a Visual KV Series expansion unit, its height becomes flush with an AC power type Visual KV Series basic unit. The procedure to attach a Visual KV Series expansion unit to an expansion unit spacer is the same as the procedure to attach a Visual KV Series unit to a DIN rail. Refer to the instruction manual supplied with the Visual KV Series for DIN rail mounting. ■ Dimensions for expansion unit spacers OP-35342 Spacer for 4-I/O expansion unit OP-35343 Spacer for 8-I/O expansion unit ø4.0 ø4.0 42.8 28 38 OP-35344 Spacer for 16-I/O expansion unit ø4.0 42.8 35 45 42.8 55 65 25.3 4 66 1-66 Chapter 2 System Installation 2.1 Installation Environment 2.1.4 Cautions on Wiring for Each Unit Visual KV Series This section describes cautions to keep in mind when wiring is performed for I/O units. Be sure to read this section before starting wiring. Wiring procedures for basic units The wiring procedures for basic units are described below. CAUTION • Turn off the power before starting wiring. • For the installation position, select a location whose ambient temperature is 0 to +50°C, whose ambient humidity is 35 to 85% RH, and one which is not subject to drastic temperature changes. • If the 24 VDC + output terminal and the 24 VDC - output terminal are switched, the power supply unit and connected units may be damaged. Never switch them. • Be sure that the sum of the current consumption of all connected units does not exceed the output capacity of the service power supply. If the system is operating in an overload status, the internal circuits may generate heat or be damaged. To recover from an overload status, disconnect some of the connected units. • Never connect the DC output of any other power supply, either in serial or parallel, to the 24 VDC output terminals. If the DC output is connected, the power supply unit may be damaged. ■ Wiring for an AC type basic unit For an AC type basic unit, perform the wiring as shown in the figure below.

Note 2: Use twisted cables to reduce induction effects. Note 3: When using a basic unit in a location with a lot of noise, the noise may be reduced by completely grounding the basic unit. Chapter 2 System Installation 1-67 12 2.1 Installation Environment ■ Wiring for a DC type basic unit For a DC type basic unit, perform the wiring as shown in the figure below.

Usually, the sum of the current consumption of all connected units multiplied by 1.5 or more is required for the power capacity. Cautions on wiring for I/O units 2 When performing wiring for an I/O unit, pay strict attention to the following contents. • • • • • Separate input lines from output lines in wiring. If the wiring for power is located near I/O signal lines, a malfunction may occur caused by the effects of a high voltage and large current. Keep I/O signal lines away from the power wiring by at least 100 mm. Separate 24 VDC I/O lines from 100 VAC and 200 VAC lines. When using pipes for wiring, make sure that the pipes are securely grounded. ■ When I/O signal lines cannot be separated from the wiring for power In such a case, perform grounding on the KV side using batch-shielded cables. (In some environments, grounding should be performed on the reverse side of the KV.) Shielded cable KV Sensor Input RL Output 24 VDC Ground Terminal The terminal screws used are M3. When performing wiring with crimp-style terminals, use the following ones. Unit: mm 6.0 maximum 6.0 maximum M3 1-68 Chapter 2 System Installation 2.1 Installation Environment Because the Visual KV Series is constructed to be sufficiently resistant to noise, it can usually be used without being grounded. However, when the Visual KV Series is used in an environment with a lot of noise, grounding is required. In such a case, pay strict attention to the following contents. • • Perform complete grounding for each individual unit. In this case, the ground resistance should be 100 Ω or less. If individual grounding is not possible, perform common grounding. In this case, the length of each grounding cable should be equal. Acceptable Recommended KV Other device Unacceptable Other device KV A Other device KV B B A A=B Complete grounding Visual KV Series Cautions on grounding A>B A<B 2.1.5 Contact Protection If inductive loads such as clutches, motors, and solenoids are used, a rush current may flow when the load power supply is turned on, or a counter electromotive voltage may be generated when the load power supply is shut down. The rush current and the counter electromotive voltage can contribute considerably to shortening the service life of the contacts. To prevent this from happening, provide a contact protection circuit. ■ Contact protection circuit examples For DC load 1 For AC load 1 Contact Contact Load Load CR circuit For DC load 2 For AC load 2 a Contact Diode b Contact Zener diode Varistor When the supply voltage is 24 to 48 V, provide a protection circuit in position "b". When the supply voltage is 100 to 200 V, provide a protection circuit in position "a". Note 1: Use a load coil whose rating is less than the contact capacity. Note 2: Use a diode whose peak inverse voltage is 10 times or more the circuit voltage and whose forward current is not less than the load current. Note 3: Individually attach diodes, varistors, and CR circuits directly to the relay coil terminal.

When performing input while setting the input time constant of an expansion unit to 10 µs, or when synchronizing the output of a basic unit with the output of an expansion unit, pay strict attention to the following contents. When inputting Visual KV Series 2.2.4 Transferring I/O Information between Expansion Units and the Basic Unit ■ When the scan time is longer than 800 µs (communication cycle) plus 10 µs (input time constant) Set the input signal ON time equal to or longer than the scan time. Scan time Receive Communication cycle in expansion unit Input signal Receive Receive ON OFF Incomplete receive OK ■ When the scan time is equal to or shorter than 800 µs (communication cycle) plus 10 µs (input time constant) Set the input signal ON time to 810 µs or longer. Scan time Receive Communication cycle in expansion unit Receive ON Input signal OFF Incomplete receive OK In the case of output The output of an expansion unit is delayed by a maximum of 800 µs from the output of a basic unit. When synchronizing the output of an expansion unit with the output of a basic unit, pay strict attention to the communication cycle. ON Output of basic unit Output of expansion unit OFF ON 800µs 800µs OFF Note: When the output ON time is 800 µs or shorter, the output may be aborted. Chapter 2 System Installation 1-77 12 2.3 Inspection and Maintenance 2.3 Inspection and Maintenance Visual KV Series This section describes the inspection and maintenance procedures for units. 2.3.1 Inspection While basic units and other units have been used for a long period of time, the connector connection area may become loose, the battery may wear out, or another nonconformity may occur in operation. To avoid any nonconformities, inspect the basic units, other units, and the wiring periodically. The major inspection items are as follows. • Check to ensure that the connector connection area is not disconnected or loose. • Check to ensure that terminals on terminal blocks are not loose. • Check to ensure that the wiring cables among units and each equipment are not damaged. 2.3.2 Maintenance While basic units and other units have been used for a long period of time, dirt will adhered. Wipe off any collected dirt with a clean, dry cloth. Wipe off any dust and dirt that has collected on small and narrow portions with cotton swabs. 2 CAUTION 1-78 Be sure to turn off the power before starting any inspection or maintenance of the units.
